Abstract

Abstract A mill for guiding the cutting of a chain saw includes a mill frame comprising a pair of longitudinally spaced, parallel members joined by a plurality of rod-like runners extending orthogonally therebetween and joined to the lower surfaces thereof. A chain saw bar may be secured subjacent to the mill frame and selectively spaced therefrom by a pair of bolts extending through the chain saw bar to the mill frame, and a plurality of tubular spacer members secured on each bolt between the bar and the mill frame. The runners of the mill frame ride on a plank secured on a log or on a previously cut surface to guide the chain saw in making planar, longitudinal cuts through a log. A slider assembly is also provided, clamped to the longitudinal members of the mill frame, and adapted to secure the chain saw in spaced relation therefrom with the chain saw bar extending downwardly therefrom. The slider assembly engages a previously cut edge of a log or lumber piece and acts as a rip fence to guide the cutting action of the chain saw.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 110 words
A device for guiding the cutting action of a chain saw which includes a chain saw bar, comprising; a mill frame, said mill frame including a pair of spaced apart, parallel, longitudinally extending members, at least one runner member extending transversely between said longitudinally extending members in the same plane thereof, a pair of end members each secured between like ends of said longitudinally extending members, at least one of said end members being slidably positionable along said longitudinally extending members; and means for securing the chain saw bar to said end members, including means for maintaining a selected spacing interval between said end members and said chain saw bar.
Claim 2
Independent Claim 110 words
A device for guiding the cutting action of a chain saw which includes a chain saw bar, comprising; a mill frame, said mill frame including a pair of spaced apart, parallel, longitudinally extending members, at least one runner member extending transversely between said longitudinally extending members in the same plane thereof, a pair of end members each secured between like ends of said longitudinally extending members, at least one of said end members being slidably positionable along said longitudinally extending members; and means for securing the chain saw bar to said end members, including means for maintaining a selected spacing interval between said end members and said chain saw bar.
Claim 3
Dependent Claim 16 words
The device of claim 1, wherein said at least one runner member extends generally orthogonally therebetween.
Claim 4
Dependent Claim 24 words
The device of claim 1, wherein said end members extend generally orthogonally between said longitudinally extending members to define a generally rectangular mill frame.
Claim 5
Dependent Claim 37 words
The device of claim 2, wherein said means for securing the chain saw bar to said end member includes a pair of first members, each extending between the chain saw bar and one of said end members.
Claim 6
Dependent Claim 20 words
The device of claim 4, wherein said first members extend perpendicularly to the plane defined by said longitudinally extending members.
Claim 7
Dependent Claim 15 words
The device of claim 1, further including a connector member extending between said end members.
Claim 8
Dependent Claim 22 words
The device of claim 6, wherein said connector member is disposed generally parallel to and spaced apart from said longitudinally extending members.
